Vendor, OOO Electrocentury-steel offers to buy tungsten electrodes, EEPS, VA at the best price. If you consider welding electrodes made of tungsten, they look like a thin rod, the surface of which there is either no special coating. Supplier of tungsten electrodes, EEPS, VA, describing the process of using the element specifies that the welding arc is formed voltava a temperature sufficient for melting metal. However, there is a supply of filler material, which acts as a welding wire. The price of tungsten electrodes EEPS, VA implies coating that provides arc stability, shielding along with the air from the molten metal.

Item description

What is the advantage and why providers recommend you to buy tungsten electrodes, EEPS, VA customers? The electrodes can be made of pure metal, but zeigeist arc leaves much to be desired, while certain additives can improve the quality of the seam and directly process, which is reflected in the price of tungsten electrodes EEPS, VAin which there is additive of zirconium. Zirconium additive, is there a recommended supplier of tungsten electrodes, EEPS, VA provides a light tan, stabilizing the arc and is used for non-ferrous metals.

Element requirements

The electrodes EEPS are available in diameters from 1 to 8 mm, tungsten electrodes VA features high stability. Offering to buy high-quality goods, suppliers of tungsten electrodes, EEPS, VA specify the requirements under which they are made:

On the surface of the elements should be no delamination and cracks, cavities and oxides, extraneous contamination, the remnants of technological lubricants.

Items must be straight, the uneven diameter should not exceed the limit deviation.

Cut the ends of the elements must be straight, it is not allowed chips, the value of which exceeds the limit of deviation.

Not allowed the presence of internal delamination cracks.
